Water has a specific heat of 4184 J/KgºC. Wood has a specific heat of 1760 J/KgºC. What material needs more energy to raise the temperature 1ºC

• wood

• water

• both are the same

A high specific heat means...

• It heats up quickly with energy added

• It requires more energy to change temperature

There are four cups of hot cocoa. The cup sizes are shown. The temperature of the cocoa in each cup is 25 degrees celsius. Which cup has the MOST thermal energy?

• Large cup (trenta)

• Venti

• small cup (Tall)

• All three are the same temperature so they have same thermal energy
